摘　　要：以太阳能热水采暖系统蓄热水箱的容积与太阳能集热器的集热面积的匹配关系为研究对象,通过数值模拟的方法,以严寒C区的赤峰地区为例,参考赤峰地区的逐时气象数据,以太阳能热水采暖系统的集热效率、太阳能贡献率为优化目标,对蓄热水箱的容积与太阳能集热器的集热面积的比值(RVA)、蓄热水箱保温层厚度等设计参数进行了优化研究。研究结果表明,在RVA为50~150 L/m^(2)的条件下,赤峰地区的太阳能热水采暖系统可获得较为理想的集热效率。研究结果可为严寒C区太阳能热水采暖系统的设计提供参考。Taking the matching relationship between the volume of the heat storage tank and the heat collection area of the solar collector of the solar hot water heating system as the research object,through the numerical simulation method,a case study of Chifeng area in severe cold area C,referring to the hourly meteorological data of Chifeng area,taking the heat collection efficiency of the solar hot water heating system and contribution rate of solar energy as the optimization objectives,the design parameters such as the ratio of volume of heat storage tank to heat collection area of solar collector(RVA)and the thickness of the insulation layer of heat storage tank are optimized.The results show that the solar hot water heating system in Chifeng area can achieve ideal heat collection efficiency when RVA is 50~150 L/m^(2).The research results can provide reference for the design of solar hot water heating system in severe cold area C.
